PAPER PUNCH on PERFORATOR.

SPECIFICATION forming part of Letters Patent No. 760,303, dated May 17,1904.

Application filed February 1, 1904..

To all whom it may concern.-

Be it known that I, CHRISTOPHER O. BOYKIN, a citizen of the UnitedStates, residing at Norfolk, in the county of Norfolk and State ofVirginia, have invented new and useful Improvements in Paper Punches orPerforators, of which the following is a specification.

This invention relates to a paper punch or perforator.

The object of the invention is in a simple,

ready, thoroughly feasible, and practicable manner to effect stabbingand punching of bills, receipts, or other papers for the purpose offiling them away upona bill-file of any usual or preferred construction.

The devices herein shown are adapted to be secured upon a suitablebacking which may have associated with it ordinary filing-wires, such asare in common use, and as this will be readily understooddetailedillustration of this application is deemed unnecessary.

With the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a paper punch or perforator, aswill be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specificatiomand inwhich like characters of reference indicate corresponding parts, thereare illustrated two forms of embodiment of the invention capable ofcarrying the same into practical operation, it being understood that theelements therein exhibited may be varied or changed as to shape,proportion, and exact manner of assemblage without departing from thespirit thereof.

In the drawings, Figure 1 is a view in side elevation of one form of theinvention. Fig. 2 is aview in perspective with a part removed. Fig. 3 isa view in vertical longitudinal section through one of the perforatingelements. Fig. 4 is a view in detail of one of the stripper-plates. Fig.5 is aview in side elevation of a slightly-modified form of theinvention. Fig. 6 is a view taken from the under side of the form ofdevice shown in Fig. 5.

Referring to the drawings and to Figs. 1 to 1, inclusive, thereof, 1designates the base of Serial No. 191,594. (No model.)

the punch or perforator, the same comprising two arms or members 2 and aconnecting member 3, the arms 2 being disposed at diverging angleswithrelation to each other and to the member 3. As before stated, it isdesigned that this device shall be combined with a holder havingfiling-wires thereon, and to effect-this result the member 3 of the baseis provided with an angularly-disposed boss 1, provided with an orifice,the member 3 being provided with a similar orifice 5, and through theoriiices thus provided suitable fastening means may be inserted toeffect securement of the device to its support. As both members of theperforator are constructed in the same manner and operate alike, adescription of one will serve for both. vided at its free end with acutter'or punch '6, which is in the form of a tubular projection havinga V-shaped crotch 7 at its upper end, the inner walls of the crotchbeing countersunk, thus presenting cutting edges. Secured to the member3 in any suitable manner, as

presenting a guide to effect proper-insertion The member 2 is proof thesheet of paper and to cause it to be properly positioned with relationto the cutter or punch, the said stripper-plate being provided with anorifice to receive the cutter or punch. 1, the stripper-plate occupiesnormally a position slightly above the upper end of the punch or cutter,and by this arrangement at each manipulation of the device the severeddisk of paper will be positively forced away from the cutter, thuspreventing any clogging thereof.

Ioacting with the cutter, which constitutes the male member of thepunch, is a female cutter member 9, which is in the form of a platehaving at its rear end underturned flanges 10, which embrace thestripper-plate and hold it firmly assembled therewith, the rear end ofthe female member 9 being provided with an upturned head-piece, thefunction of which will presently appear. One side of the female memberis provided with a As will be seen by reference to Fig.

downturned arm which is bent under the memher 2 and subserves the doublefunction of limiting the upward movement of the stripper-plate and thefemale member and also the insertion of the paper to be punched andforms, therefore, a combined gage and stop, by which term it will behereinafter designated. In the operation of the device the disks orcircular pieces of paper severed from the bill or receipt or the like tobe filed would ordinarily fall to the floor or upon the desk of theuser, and thus be objectionable, and to obviate this there is awaste-holder 13 combined with the female member, the same comprising asemicylindrical metallic body having its edges outturned to presentflanges 14,

\ which are adapted to engage inturned guides 15, formed on theupperedges of the female cutter member. As shown in Fig. 52, one of theflanges 15 extends practically throughout the greater portion of thelength of the female cutter member, while the other guide is more in thenature of a lug; but it is to be understood that the invention is not tobelimited to this particular arrangement, as elongated guides may beemployed on each side of the female member, or, if preferred, aplurality of short lugs or guides may be adopted, if found necessary ordesirable. The female cutter member is provided with an orifice 16,through which the cutter or punch is adapted to project; but owing tothe peculiar configuration of the cutter or punch it is not essentialthat there should be any direct contact between it and the walls of theorifices of the stripper-plate and the female cutter member to effectsevering of the disk from the paper, as owing to the double-pointedcutting edges presented by the V-shaped crotch and the beveling orcountersinking of the inner walls of the said crotch a clean-cutsevering is eflected, which could not result with an ordinary tubularcutter except there be a direct contact between the cutter and the wallsof the orifices in the stripper-plate or of the female cutter member. Inorder to prevent the escape of the cut paper, the head 11 is provided,against which the rear end of the waste-holder will impinge, and when itis desired to clear the waste-holder of the accumulated severed disks itwill be only necessary to impart a slight compressing of the outer wallsof the waste-holder to remove the flanges thereof from engagement withthe guides, whereupon the cutter-holder may be relieved of its contentsand replaced to its original position.

The form of my invention just described is adapted for punching twoholes through a sheet of paper at the same time, and to effect this thepaper is held in thehand and inserted between the female cutter memberand the stripper-plate with the written side down, and as soon as theforward edge of the sheet impinges the combined gages and stops pressureis applied by the thumb and forefinger of each hand to the waste-holderand to the under side of the members 2, thereby forcing the cutters orpunches through the paper and discharging into the holders the severeddisks. As soon as the pressure is released from the parts the femalemember and stripper-plates resume their former positions, and thus leavethe sheet of paper free to be removed and to be filed upon the filingdevice, whatever character it may be.

In the modified form of the invention shown in Figs. 5 and 6 there isprovided a punch or perforator adapted for forming a single opening, andthis will be found highly useful where papers are to be secured togetherwith string, tape, or ordinary paper-fastener. In all essential respectsthe punch forming this modification is the same as one of those shown inthe form of invention first described, the main difference being thatthe waste-holder is omitted, although, if preferred, it may be included.There is also a slight difference in the construction of the combinedgage and stop, for whereas in the form of invention shown in Figs. 1 to4:, inclusive, there is one stop employed in connection with eachpunching element in the form of the invention shown in Figs. 5 and 6there are two gages 17 and'18, whereof the gage 17 constitutes a stopfor limiting the upward movement of the stripper-plate 19 and femalecutter member 20 with relation to a base 21.

The devices described are exceedingly simple of construction, and byreason of the manner in which the parts are made and assembled danger ofthe disarrangement in use will be reduced to a minimum. Moreover, incase of an injury repair of a part may be cheaply eflected, as it isdesigned that all the parts shall be made of standard sizes, and thus incase one or more parts become useless repair may be readily and cheaplyeffected.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a paper-punch, the combination of a base having a cutter, astripper-plate secured to the base, a female cutter member secured tothe stripper-plate and provided with a pro jecting arm for engaging theunder side of the base to limit the movement of the stripper-plate andfemale member, and a wasteholder detachably connected to the femalemember..

2. In a device of the class described, a base carrying a tubular cutteror punch having a crotch provided with interiorly-beveled walls, aresilient stripper-plate secured to the base and having an orifice toreceive the cutter or punch, a female cutter member secured to thestripper-plate and provided with a head, and a waste-holder detachablyconnected with the female cutter member and adapted to have one endclosed by the head.

3. A device of the class described comprising a base provided with acutter, a stripperto the base, and a waste-holder engaging the IQ guideson the female cutter member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
